Marius Strobl bba6f0a901 - Add a new method ofw_bus_default_get_devinfo() that allows to retrieve
a newly introduced struct ofw_bus_devinfo which can hold the OFW info
  of a device recallable via the ofw_bus KOBJ interface. Introduce a set
  of functions ofw_bus_gen_get_*() which use ofw_bus_default_get_devinfo()
  to provide generic subroutines for implementing the rest of the ofw_bus
  KOBJ interface in a bus driver.
  This is inspired by bus_get_resource_list() and bus_generic_rl_*_resource()
  and allows to reduce code duplication in bus drivers as they only have
  to provide an ofw_bus_default_get_devinfo() implementation in order to
  provide the ofw_bus KOBJ interface via ofw_bus_gen_get_*().
- While here add a comment to ofw_bus_if.m describing the intention of
  the ofw_bus KOBJ interface.
